Friendship!

this site has helped me learn how to pick out a scam easily and ignore it couldn't tell you how to block them all though the address is www.workathomenoscams.com it has some listings of real online work companies and theres parts that teach you how to avoid scams and reviews on websites that tell you weather they are a scam or not in this site owners opinion hes a successful affiliate marketer which is i think working on a free training program for that as well. its also how i found this site :)

If you use Firefox, install WOT. that will they you if the site is untrusted or not.
